Sending mail from a different address in Gmail
Click the gear icon in the upper right, then select Settings.
Select the Accounts and Import tab (or Accounts tab, if you're using Google Apps).
Under Send mail as, click Add another email address.
In the 'Email address' field, enter your name and alternate email address.
Choose one of two options:
Use Gmail's servers to send your mail (this is easier to set up)
Use your other email provider's SMTP servers (we recommend this option for professional mail accounts or domains). Note for Google Apps users: Depending on your domain2 type, this feature may be disabled by default. Talk to your administrator if you have any questions.
